Hi folks, What’s the difference between WISA and Wireless Powerlink? I.e. when is it one and when is it the other, for instance when using a Transmitter 1 and WISA enabled B&O speakers such as BL18 & 19? Does it depend on the switch on the T1 for ‘B&O system’ vs ‘non-B&O system’? I’ve got my BS Core hooked up via optical at the moment so I’ve got it set to ‘no’ because I figured optical was best for quality but that would mean it would be no different to any upstream preamp connected via optical.  Have I got that right? Is there any functional benefit to connecting the BS Core to the T1 via Powerlink? I was just trying to avoid pointless DA and AD conversions. Thanks!
